Example of inheritance with two child (derived) classes in Python

Here, we are going to implement a python program to demonstrate an example of single inheritance with one parent (base) class and two child (derived) classes.
Submitted by Pankaj Singh, on June 25, 2019

In this program, we have a parent class named Details and two child classes named Employee and Doctor, we are inheritance the class Details on the classes Employee and Doctor. And, finally creating two objects of Employee and Doctor classes and setting, showing the values using their methods.

Python code to demonstrate example of single inheritance with two child classes

# Python code to demonstrate example of 
# single inheritance with two child classes

class Details:
    def __init__(self):
        self.__id=0
        self.__name=""
        self.__gender=""
    def setDetails(self):
        self.__id=int(input("Enter Id: "))
        self.__name=input("Enter Name: ")
        self.__gender=input("Enter gender: ")
    def showDetails(self):
        print("Id: ",self.__id)
        print("Name: ",self.__name)
        print("Gender: ",self.__gender)

class Employee(Details):
    def __init__(self):
        self.__company=""
        self.__desig=""
    def setEmployee(self):
        self.setDetails()
        self.__company=input("Enter Compmany Name: ")
        self.__desig=input("Enter Designation: ")
    def showEmployee(self):
        self.showDetails()
        print("Company: ",self.__company)
        print("Designation: ",self.__desig)

class Doctor(Details):
    def __init__(self):
        self.__hospital=""
        self.__dept=""
    def setDoctor(self):
        self.setDetails()
        self.__hospital=input("Enter Hospital Name: ")
        self.__dept=input("Enter Department: ")
    def showDoctor(self):
        self.showDetails()
        print("Hospital: ",self.__hospital)
        print("Department",self.__dept)

def main():
    print("Employee Object: ")
    e = Employee()
    e.setEmployee()
    e.showEmployee()
    print("\nDoctor Object: ")
    d=Doctor()
    d.setDoctor()
    d.showDoctor()

if __name__=="__main__":
    main()

Output

Employee Object:  
Enter Id: 101  
Enter Name: Prem Sharma 
Enter gender: Male
Enter Compmany Name: IncludeHelp 
Enter Designation: Technical writer 
Id:  101 
Name:  Prem Sharma
Gender:  Male  
Company:  IncludeHelp
Designation:  Technical writer

Doctor Object: 
Enter Id: 201  
Enter Name: Amit Shukla 
Enter gender: Male
Enter Hospital Name: APOLLO
Enter Department: Doctor
Id:  201 
Name:  Amit Shukla
Gender:  Male
